Cricket Australia (CA) confirmed on Monday that Nathan Lyon will miss the remainder of the Ashes series due to a significant calf injury.

During CA’s ongoing away Ashes campaign, which they are leading 2-0, their squad was tweaked.

As a result of the tweaks, reserve batter Matthew Renshaw has also been released from the squad, but he will remain in England and be available in the event of an injury scare on the tour.

Since Lyon has no substitute, Todd Murphy, who played well in his first Test series in India earlier this year, will enter the lineup in Lyon’s place.

“It’s not looking good at the moment, it’s a significant tear in the calf, and it’ll end the series,” Andrew McDonald said. Todd Murphy is expected to replace McDonald for Thursday’s third Test at Headingley.

The spinner adds a different balance to our attack, and as you saw on Sunday, we had to do things differently without Nathan Lyon down the other end, which we’ve been used to.

There was a bit of chaos at times, so we enjoy having that spin option.”

Inglis returned to Perth following the first Test to give birth to his first child, and no replacements were added to Australia’s squad.

As the second Ashes Test continued on Friday, veteran off-spinner Hamish Watson arrived on crutches at Lord’s.

While getting medical attention on the boundary after sustaining a calf injury during the second session on Thursday, Nathan Lyon looked distraught as his teammate Steve Smith hinted Lyon might be out for some time.

Nathan Lyon was spotted hobbling out with the physio shortly after completing his spell after completing his 37th over. Lyon was taken off the field as he chased a ball to the fence in apparent distress.

Nathan Lyon limped into Lord’s pavilion on crutches on Friday morning, joining his teammates. He was also wearing a bandage on his right calf, and Australia is expected to provide an update on his fitness in the coming days.

In Wednesday’s match, he became the sixth player and first ever bowler to play 100 consecutive Tests.
